Does anyone know games exactly like A Town Uncovered?
Nothing *quite* like ATU, but many have similar aspects.
Summertime Saga is close enough that ATU is often considered a copycat production. Comparing the two, it seems like a mainstream-version of ATU. The world is filled with big-boobed, lusty women who inexplicably want the MC’s dick and don’t look at another man regardless of how sex-positive they are. The father is conveniently dead, the aunt lives alone, the hot woman you deliver pizza to is a single mother, as is your neighbour. There are exceptions, but overall, the husbands you encounter are in sexless/unfullfilling marrriages. (Tony is impotent, the police wife is strongly anti-sex, the sexualized maid somehow managed to always escape the mayor’s attentions, the fish monster never found a mate…) Similarly, the story completely depends on the MC. He actively does everything and he is the single point of failure. He saves the various projects his teachers work on. He frees the maid from the mayor. He investigates the murder and corruption. He brings his aunt success etc etc. There are exceptions, but they are rare. Basically, the world and characters revolve around the MC.
This is in stark contrast to ATU. At least the first few segments of every storyline, including the majority of the main story, is a sort-of walking simulator. You witness the world that acts around the MC, and the other characters are much more dynamic and active than the MC. Half of the mother route the MC having to deal with the demands of a moody mother and aggressive father. The sister and Allaway route are more active, but even there the other characters
do things and the relationship often progress through the simple act of witnessing what they are doing. The MomxSis route and the main story are the most extreme examples of this, though at least the main story seems to intend for the MC to act in an active role in the future. As it is, the world feels much more dynamic, I find, but the MC feels bland like soggy white bread.
Insexual(/Incestual) Awakening focused even more on the passivity/others acting on the MC, from what I recall. It also didn’t have any overarching threat or plot beyond various family members suddenly realising they really want to "explore their sexuality" with the MC. He does what others tell him to do, then pops a boner, then they do something sexual.
Town of Passion also features the MC walking around the town and starting relationships with characters while an overarching threat needs to be fought, but I the manner it does so is quite different. The MC is literally the Chosen One™ as well as only male resident. He has to solve the quests and train because that is what a Chosen One™ does and because a lewd goddess tells him to. Also an RPGM game with various "find the object" or "complete the puzzle" type quests.
I’m unfamiliar with Urban Demons, but it seems to be a corruption type game, which is quite different to any of the above.
Regarding other games that might be considered vaguely, sort-of similar:
Fantasy Valley is another Point&Click game in which you play as a young student, who is new to the city, has to investigate/solve an overarching threat and meets plenty of new characters. The world feels less sex filled compared to ATU/SS/IA, but there is still a lot. The game features a pleasant mixture of actively doing stuff and witnessing how others do stuff. The story is very different and extremely linear, but it playing through it I liked in a similar way as I liked ATU.
Solvalley School is another dating sim sandbox game. There is no big plot or goal, it’s just the MC messing around with various girls. I’m mentioning it mostly because it might scratch the itch of those who desperately want more sexworld content. The situations and characters are absurd. The MC has no morals beyond "fucking girls = good" and the women all crave a big strong man with an enormous penis (openly or secretly).
Life in Woodchester seems to be intended to be a game styled after Summertime Saga and the parts I played felt similar enough, but the custom game engine didn’t run well on my machine. Might be worth checking out.
